    • Its good.
Is compatible with all KWC OEM 1911 guns. No leakage.

    • Very well made
Exactly what I needed, at a quarter the cost anywhere else. Arrived early, fits just like the original, built to last, and most importantly, functions exceptionally.

    • Excellent magazine, exact replacement/additional for the pistol
These magazines are the correct OEM magazines for the Sig Sauer We The People CO2 pistol. They have good seals and last a long time when properly cared for. Make sure to use Crosman Pellgunoil when inserting new CO2 cartridges to keep the seals in good condition. I have had no issues with these magazines. ... show more

    • DONT BUY‼️‼️‼️
Review Image by Troubles where expected Troubles where expected
Don't buy!! The mag broke within the first week of use!!! I didn't even tighten with excessive force when it broke. The CO2 wasn't even completely sealed before the magazine broke. Cheap cast aluminum material.

    • This item will fit and work for other models using this magazine. Period.
I have the Umarex Colt Commander model and purchased a couple at a “great” price for a comparison as other sellers present them for over $30. The Colt brand is even higher priced in most cases. The exception was the seller I got these from. Excellent price. So why not check it out? As it turns out they are as near a same product, if not the same, as can be examined visually and they work perfect in my Colt. My suggestion: shop around for prices to suit your budget. I purchased 2 for a few bucks more than the low end retail price of one magazine. Good luck. Be safe, have fun and blast away with whatever name brand you use! 😎👍 ... show more

    • Great mag replacement for the air pistol
The Sig Sauer Factory Replacement Magazine is a lifesaver for anyone who relies on their CO2-powered metal BB gun for fun or training. When my original magazine started to give out, I turned to this replacement, and it worked like a charm from the get-go. The build quality is solid, and it fits snugly into the gun without any issues. Loading and firing with this magazine are smooth and reliable, just like the original. Whether I'm plinking in the backyard or practicing my aim at the range, I can count on this magazine to feed BBs consistently and keep the fun going. Plus, knowing that I have a reliable replacement on hand gives me peace of mind for future shooting sessions. If you're in need of a dependable CO2 magazine for your Sig Sauer BB gun, look no further than this factory replacement—it's a game-changer for the price. ... show more

I have to put t stars because they don't fail ? The valves do . I wish the replacement valves were listed cheaper because they would sell more of them ...good clip if you follow its rules . Don't leave them full gased

    • Really good quality
Product worked well without any any flaws and also came with an all on key to tighten up the co2 cartridge. This magazine can also work with other Cybergun 1911s perfectly and shoot as long as they are .117 caliber. This is the cheapest you can get if you get free shipping, on other websites it costs the same which is $19.99 but turns out more expensive because they ask to purchase $99 or more worth of products. The shipping cost is about $7.99 depending on the websites but here you have to spend $25-$35 which is really to past. ... show more
