Great product.On Form Rifle Chiappa Rhino Combat / Concealed Carry GripAAlowVerified Buyer5.0 star rating04/12/25Great fit on my FuseReview by Alow on 12 Apr 2025 review stating Great fit on my FuseI 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!On Mirzon Sig Sauer P365 Hybrid Polymer Grip Module - BlackDDustin P.Verified Buyer4.0 star rating04/12/25Good to goReview by Dustin P. on 12 Apr 2025 review stating Good to goAside from the guide rod plunger being stuck everything works as expected.On Shadow Systems MR920/XR920 9mm Barrel & Comp Assembly - BlackWWadeVerified Buyer5.0 star rating04/12/25Quality FinishReview by Wade on 12 Apr 2025 review stating Quality FinishNitride 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.On Faxon Firearms 6.5 Grendel 9310 Bolt- NitrideJJacob M.Verified Buyer5.0 star rating04/12/25Good productReview by Jacob M. on 12 Apr 2025 review stating Good productFits perfect and is well madeOn Gas Tube - Stainless Steel$329.99 -
