The gun had lots of metal parts and had good weight to it. The gun also had nice attention to detail, felt sturdy, and had a full sized style magazine instead of a flimsy stick magazine. The gun shot pretty strong as it penetrated both sides of a soup can before lodging the BB into a wooden backboard I set up for plinking.

Unfortunately, the gun ceased working after the second magazine I used right of the box. In particular, the trigger appeared to be "jammed in" and would not retract to allow me to squeeze the trigger to fire the pistol. Since it was brand new, I made zero attempt to tinker with the gun and returned it to Airgun Depot for a return. The return process was quick and trouble free as Airgun Depot promptly sent me a prepaid FedEx shipping label. Very happy that Airgun Depot stepped up to stand behind its products.

This gun is fun to shoot. You can field strip it so you can keep it in good condition. It is temperamental. When putting the mad in the gun, you have to baby it. Often I have to remove the mag, take the slide off and make sure everything is lined up. Don’t get me wrong, it’s fun to shoot and super cool, just it’s kinda Whimsy.

Field stripable Nice weight Fairly accurate Nice price. Soda can?s worse enemy Works best with Hornaby black diamond bbs

Needs to be babied a little. Making sure you have the right BBs is essential

Heft and feel out of the box was excellent. Shot a little high at first. Mounted a Low Profile pistol laser and zeroed. Was on target after that. Great Gun!

Great feel

None at this time

By DennisUSAAugust 12, 2014

It looks good, feels good, is easy to load, and gets lots of shots per Co2 cartridge. Shoots a little high, but grouping is nice. A+ 5 stars !

Everything, it's a perfect pistol.

Can't think of any.

By JonUSAMarch 14, 2013

Very nice gun to use and a great value. Nice gun to add to my collection.

Weight and feel Shoots great and accurate for me


By BrandonUSAAugust 21, 2012

Great gun for the money. Has a good weight and feel. Trigger is hard to pull. However, it has improved my grip & trigger finger. I can now shot one handed very accurate. Clips contain the CO2 cartridge and are solid. This is really nice when using 2 or more clips. 22 shots go fast when you're having fun. I mounted a green laser on the rail for fun. Great tool for showing how shaky or stable your grip is. It also makes the gun look mean! With the laser turned on and the BAX system on the end of the gun, this pistol looks very real. One more nice thing is that the packaging can be used to store the gun & extra clips. 9 out of 10

Realalistic feel.

Trigger is plastic.

By DavidSeptember 3, 2011

Shot way high out of the box. I had to build up the front sight blade with JB Weld, and now it's very accurate. The trigger pull is brutal and can affect accuracy. However, I think it's great for forcing you to concentrate on your trigger technique. This gun looks and feels like the real thing. Also, I'm getting 150 shots per CO2 cartridge.

What is the length of the barrel? I can't believe the attention to detail is kept being left out. It is difficult to order as an informed buyer if the barrel length is listed as 0.0. Somehow I hate to ASSUME that I might get a pistol with a 36 inch barrel length. Hello! And thank you in advance.

Is it 12gram co2?

asked ultimate from Sweden


Mark from USA

How Reliable is the mag ? I know Walther Umarex, German, Austria , Swiss made items are a Fine design as a Swiss watch ! I know this Sig it is not a blow back, but I like the Blow back guns. My Gamo 1911 Govt Model wore out on the top chamber tank with jed weld and some Machining( dremel sanding worked) but the same wear mark open up the same crack why i wont buy another blow back even after i used Lithium to help lube for friction on my Gamo and other Air Guns I use the V model know as a Dry Fire and practice reloads with mag . I have Real Sigs in DA/SA and 1911 and Colts Etc. Pistols , any Gun will do. I like To use BB and Pellet to practice my trigger control as Air Pistols have a Different Trigger Pull So it really works on A Firm Press and Strengthen your Finger and Grip ! A Big Improvement In Live Firer training with hand guns . So Yes I like To train with Air soft and BB Pistols and revolvers ( and Realism helps your Muscle memory) as Ammo is not going to keep coming down as Buying has slowed way down as Our Economy has crippled a lot of Gun Owners !

asked Vrmnt Hntr 45 from USA

What type of co2 cartridge dose it use? Thereaded?

asked Steve

Is this is using CO2 .. how much is the CO2 refill and the BB bullet ?

asked Nelson

CO2 can run from $0.45 to $1.00 depending on how many and from whom you buy. BBs, $9 for 6,000, so you'll need 6,000/100 shots = 60 12 gram powerlets for the best economical amount of BBs. You don't want to end up with excess BBs and no more powerlets, or worse, out of BBs and a truck load of 12 gram CO2 powerlets; you'd then have to get a 1 inch pvc pipe and set up for a mortar.

How much of this gun is metal ?

asked John

Most of it is metal, the trigger guard and pistol grip area is plastic though. Everything else is metal.

Tony from USA

Is this a blow back system? It doesn't say either way. What do you think of the item?

asked Jerry C. Franklin

Nope, no blow back. Still this gun is pretty awesome. Great weight and feel to it, plus it is relatively cheap for a metal gun. The mag drops out and slides in like butter. I would recommend it.
