I paired the slide with a Mischief Machine Commander complete with Patriot Defense BRASS (Black Cerakote) Grip Panels, what a beautiful piece.On Norsso Sig Sauer P320 Compact pBentham RMR Slide - Black DLCSSean R.Verified Buyer5.0 star rating07/12/25Love it, perfect quality, looksReview by Sean R. on 12 Jul 2025 review stating Love it, perfect quality, looksLove it, perfect quality, looks awesome!On Norsso Reptile XP RMR Slide For Glock 19 Gen 5 - Black DLCAAdam U.Verified Buyer1.0 star rating07/11/25Defective JMAC Threaded Mount – Manufacturing Flaw on First ThreadReview by Adam U. on 11 Jul 2025 review stating Defective JMAC Threaded Mount – Manufacturing Flaw on First ThreadI recently purchased a brand-new JMAC mount from Rainier Arms and ran into a serious issue straight out of the package. When attempting to thread my Resilient RS9 suppressor onto the mount, I immediately noticed significant resistance. My first concern was potential cross-threading or an incorrect thread spec, but after double-checking compatibility and verifying that the threads were properly aligned, the problem persisted.
Upon closer inspection with a pick, I discovered that the resistance was coming from the very first thread. There's a small but clearly visible dent or deformity in that area—deep enough that even after a careful attempt to smooth it out, the defect remains. This is not a burr or damage from improper handling; the mount was installed using proper tools, and the threads were never touched until I attempted to mount the suppressor.
Frankly, I’m extremely disappointed. For a premium product at this price point, JMAC’s quality control should be far better. This kind of defect should never make it out the door.
I’ve reached out to JMAC directly and hope they will stand behind their product and provide a timely resolution—ideally a replacement. I doubt Rainier Arms will assist, as they're just the dealer, but I expect JMAC to take responsibility.On JMAC Customs 360HD 1/2-28 FaceMount HUB$400.00Out of stock -
