The ICS PM2 makarov is as quiet as the MK23. The only downside is that it doesn't have the after market support. The MK23 can be made to out perform everything. The PM2 scores very much on style and is a lot smaller. It takes a CO2 bulb but will chrono no problem. It has a very heavy trigger if you want to rapid fire it so it's better to cock the hammer with your thumb. If it had the same after market support as the MK23 it would probably be the go-to sniper backup but that doesn't look like it's going to happen. Still if you want something smaller than the MK23 and just as quiet, but don't need it to perform circumcisions at 70 meters it's an option. I like mine. I did buy the larger suppressor for it. And the magazines are little sticks that are very easy to store.
