Great fit on my Fuse

Review by Alow on 12 Apr 2025 review stating Great fit on my Fuse
I grabbed one of these for my fuse so I could run my shorter mags for summer. What a great grip. Fills the hand but isn't cumbersome or too weirdly shaped. It had one high point that poked me from the beavertail but about a minute and a file and its all comfortable now. Fits the 12s flush but can take any of the larger mags. It can take a x300u but fits my carry lights like the tlr7sub just fine. Highly recommend!

Aside from the guide rod plunger being stuck everything works as expected.

Quality Finish

Review by Wade on 12 Apr 2025 review stating Quality Finish
Nitride finish is absolutely perfect. Looks every bit as good as Maxim and JP 6. 5 Grendel but with a better finish. Only time will tell how good it really is as to how well it hold up to thousands of high pressure reloads. Based upon looks alone it is 5 stars. I will try to leave a updated review at 2,500 rd mark as that is when extractors begin to break on more expensive brands.
