Springs seem to work fine, factory glock magazines still dra
Springs seem to work fine, factory glock magazines still drag on slide. Pistol slide locks back with rounds still in the magazines, pistol is one of the first runs, I’m possibly hitting the extended slide lock lever under recoil? I would like to try the low profile slide lock to see if that solves the problem? I like the pistol but can’t trust it yet. The small issues are frustrating.

Response from Fusion Firearms
Thanks, David. Glad the springs are working well. Magazine drag and early slide lock are things our team can help sort out. Call us at 941-485-2579 and we will walk through it with you.

Excellent pistol!
She runs beautifully! Love this pistol, has easily become my favorite to carry! Only thing I'm bummed about is I can never find the standard compensator for the xp pro in stock. I look almost daily but no luck as of yet. I would really love to purchase one and hope to see them in stock soon! Amazing pistol with excellent quality! ????

Amazing Guns and even better customer service.
I purchased a fusion XP pro a few months ago I started shooting it, and it was a little kinky with my spring with a suppressor. A friend of mine introduced me to Ron the lead builder at fusion I brought my ex pre-pro into him and told him what the problem was he literally stripped it polished. It did all amazing things to it took it out back, fired it now it fires like a dream couldn’t ask for a better firearm couldn’t ask for better customer service thank you guys can’t wait to buy my next gun.
