Customer video review of STI 2011 Brass Magwell | IPSC/USPSA Open

Really nice magwell! Huge opening! Would love it to be a little bit taller to block the hand but it is a great addition!

Customer video review of STI 2011 Brass Magwell | IPSC/USPSA Open

Makes a very nice balance to the polymer grip. Overall fit and finish top notch. Note that black finish is very delicate and will wear fast. Got some brass colored spots before it even was installed.

Customer video review of STI 2011 Brass Magwell | IPSC/USPSA Open

I took a chance & bought one to try on my staccato’s. Fits like a glove on full size grips both gen 1 & 2. Did not fit on my C2 unless I did a little dremeling.

Customer photo review of STI 2011 Mag well | Brass | IPSC/USPSA Open Division

Love the weight and angles of this magwell. Works great on my Chambers Custom NightFighter. It can be a little difficult getting the pin back on but once it’s installed it stays put. I’m very happy with this magwell.

Customer video review of STI 2011 Brass Magwell | IPSC/USPSA Open

Magwell is great It’s a tight fit and could be made to line up with the pin hole on the grips little better. Other than that I love it. It’s huge and the weight helps with recoil.
