Staccato CS W/PMM Comp

Review by RG2 on 21 Jun 2025 review stating Staccato CS W/PMM Comp
Sent my CS to Staccato to add a threaded barrel with the intent of adding a comp. Decided on a PMM comp as they had one specifically for the C model. Both the the C and CS are the same at the muzzle but this was listed as not working on a CS due to the shape of the guide rod end as mentioned on another review. As the slide racks the corners of the stock guide rod would make contact with the comp hence not compatible. The DPM System not only fixed this but gave me the opportunity to dial it in. I am very pleased with this set up. It has been great with no issues and is an improvement over stock. The fit and finish are top notch!

Not worth the money or the shipping fees to return kit.

Review by Ryan O. on 17 Jun 2025 review stating Not worth the money or the shipping fees to return kit.
After installing shifter kit, the paddle is very loose and I am NOT confident that the paddle will remain in place on the flashlight. Also, as is misleading in which side of the flashlight it goes on. I ordered the left side thinking it is for the left side of the flashlight when it is on the pistol in my hand. Apparently it is for the left side of the light when you are looking at the lense of the flashlight. Again, VERY misleading.
