I believe in all things 3 lug for pistols. I learned something last night on how they actually work. I picked up a YHM R9 to use on my MPX and put the YHM 3 lug adapter in the suppressor for a little range testing. The 3 lug got very very sluggish to snap tight on the muzzle device, so much so I had to pull the can forward to get it to lock. I wasn't exactly thrilled about it but did a few more rounds to finish off my testing. I then put the suppressor on my SP5 and noticed something very wrong. The SP5 has a dual threaded/ 3 lug muzzle and I shoot with the 3 lug like intended with the thread protector removed. The suppressor had over a quarter inch of play off center line of the bore. I didnt shoot it out of fear of a baffle strike. Fast forward to tonight. I get the 3 lug suppressor adapter down and take it apart to find the the sleeve that applies pressure to the 3 lug to attach it, and also to center it on the muzzle forward to the 3 lug on the barrel, almost seized in the mount. I put some oil in it and ended up taking a brass punch and hammer to drive it apart and it was BONE DRY. A lite coating of grease and moving it back and forth by hand a few minutes got it nice and slicked up.
Notes. If it does not feel right, stop and check. Make sure the system is operating is designed, and a little lube goes a long way.
On the SP5, to get the suppressor to center on the muzzle, the thread protector must be installed to keep in center line to the bore.
See pics for reference. Hopefully this will help someone before they end up with a baffle strike or worse.
