Our take:  The WE 1911 Hi-Capa 5.1K-Tac, perhaps one of the most unique looking pistols from the WE 1911 collection, is an amazing pistol to both see and wield.  The 5.1K-Tac features a signature unique DRAGON textured front end, which is full metal and extremely intimidating.  The full metal slide and frame are designed to increase power and accuracy, while controlling recoil so that the pistol is extremely stable and accurate during shooting.  The polymer hand grip is sturdy and comfortable, resulting in a very secure grip with minimal effort.  The chamber, safety, slide stop, hammer, trigger, barrel, are also quality-manufactured from reinforced metal in order to replicate the solid, full metal feel of a real M1911.

WE Tech has also upgraded the internals to reflect their dedication to high-performance.  They have reinforced the recoil and hammer springs, improved the structural rigidity of the firing pin, and installed a high flow valve to maximize performance and durability.  The safety is easily accessible, in typical M1911 fashion, and as always, there is a functional lower tactical metal rail for easy tactical accessory (laser, flashlight, etc) mounting.

The culmination of all of WE Tech's knowledge of the gas blowback pistol and Caspian Arms' rock-solid durability has produced what we think is arguably one of THE MOST WELL-ROUNDED gas blowback pistol line-ups on the market.  An integrated rail on the frame of the pistol (railed frame) allows for easy laser/flashlight mounting.

You get the best of both worlds (performance and realism), with no compromise made to quality or durability.  To put it in simpler terms, it shoots hard, it kicks hard, and yet it is still extremely accurate.

5 350 FPS WE Hi-Capa 5.1 Full Metal 1911 Gas Blowback Airsoft Pistol *****
Just beautiful

"Now I don't have a huge amount of experience with gas pistols, but this thing is the I've seen by a long shot. The thing is massive, every bit of two and a half pounds, but that one of the things I love about it. Just get a good fitting holster for it so it doesn't jump around too much when you're running. Out of the box, it's dead on accuracy wise. Flat shooting, even if the FPS is just a little slower than some other pistols. I've only run CO2 through it so far, and it gets about a mag and a half to two mags before you need to swap cartridges. The flared mag well making reloading so smooth and easy that you almost can't wait to run dry and have to reload. The action on this weapon is tight and precise. The only thing that's happened so far in the way of a negative feature is the safety switch on the right side is a little loose. No effect on the left switch though. I absolutely recommend this pistol to anyone looking for a high quality sidearm or even primary weapon."

A Year Later

"I've had this pistol for a little over a year now and I must say it's been through hell and back. It's been dropped 4 times onto concrete, fallen into dirt, into water, and still performs extremely well. It's had parts broken off and replaced over the year: the iron sights, the right thumb safety, and the hammer, but the great thing about Marui clones are that parts are available everywhere and for cheap. Overall I am extremely impressed with the durability of this pistol and you can get it for less than a hundred dollars."

Great Buy

"Updated 11.14.2011: This is still a very good gun. Issues: 1) The inner barrel is a little short, could use a 1/8 inch extention. 2) The bottom rail, because of the blowback repeated action, comes loose after a period of time. The two screws holding it in place are not sufficient. (Thank you) This is a very nicely made gun. Very detailed, balanced... All around well crafted. I was very impressed with the power, more powerful that I thought. Very precise, the blowback feels good, very rapid fire. Also, when you buy a Gas blow back gun, buy an extra clip. Also if you have the funds for it, also buy an CO2 clip, so you may go to any Shooting range to practice, or @ least here in Florida all Shooting range accept CO2 Blowback guns to practice in the range. I will highly recommend this gun, and also Airsoft Megastore. I had a couple of questions and they were really helpful. Shipment went out same day and was delivered on time. Thank you very much."

"Yes, i have 1 already, and ordering another. my current one not working so well, but that is my fualt. It is designed well and works great. good accuracy. You get over 33 to 36 shots fired charge on the clip, more then it holds. Of course, this is using the correct Green gas for the the tempature your firing in. Only small thing i have found wrong, and not sure what is wrong yet, and what happend yet is the firing Mechanism. Located in the back half of the slide. its jamming forward and not returning. This may be lack of oiling, or defect, dont know yet. But a new one is only 20 bucks also, not bad. all the 5.1 are the same, just different outsides. ive already ordered new parts for the one i have, and will write a reveiw after i examine the problem. Still a good gun, just take care of it, and oil it properly. "

The store is amazing. I have found there items that I could not find in other stores which makes it the best. I have made questions and inquires about products and the customer service has responded super fast with accurate answers. All my products have arrived in excellent conditions in spite of other stores. My last product came late because it was rescheduled but that was UPS fault I think. I would like to thank Matthew for his exceptional customer service. Whenever you need help, please try to contact him. My advice, buy in Airsoft Megastore, they have coupons and the widest variety of airsoft products. RandyLoy, USA
I ordered a gun sling a couple weeks ago. Unfortunately, one of the clips broke. After a few email correspondings with a customer service representative named Jun (my emails did not show a last name), AMS sent me a replacement sling for free. I did not even have to send my clip back. AMS is a terrific store and I plan on doing more business with them. They were polite, efficient, and just a pleasure to work with. I would recommend Airsoft Megastore to anyone. mskanwischer, USA
Airsoft Megastore is The Best Airsoft Website Out There (I Think) and i Will Always Be Loyal to AMS and Order Almost All of my Gear From Them. The Customer Service is Also Amazing, Jun my Customer Service Representative Has Helped Me With Anything i Needed Help With, Especially My Order Problem (Had 2 Magazines Missing from Order) and Jun Helped Me With The Problem, and Now The Mags Have Been Shipped To Me. Thank You So Much AMS and Jun. Ethan1214, Saskatchewan, Canada
I love that Airsoft Megastore has videos of most any information you will need to learn and care for your products. I purchased an AEG for my son and in short order, unfortunately, it began grinding after brief use. I emailed for warranty repair with symptoms and with 24 hours (22 to be exact) I received an email explaining possible causes with a video like for tuning the gun. I had the gun working again within 15 minutes, avoiding returning the gun and the mess associated with returns\repairs. Excellence on Sean's part to help out a first time customer of theirs. Highly recommend. bucfanjeff, USA
Everything worked great, shipping was super fast. I am very pleased and won't hesitate to order through airsoft megastore again. rob_riley, USA
