In a related thread I had asked about which suppressor would be best in 9mm between a SWR Trident 9 and a Gemtech. I think I jumped the gun (no pun intended) and should have thought about it a bit more. I was wondering between 9mm and .45, which one would be better as a first suppressor? I'm looking at the YHM M2 Cobra in 9mm and .45 because there is a local dealer who can get them cheaper than I can find other brands of suppressors. I see a few pros and cons for each: With the 9mm, I have more platforms to use the suppressor with (G17, G17L, 2x G19, G26, G34, Sig P228) but there is the caveat of having to use 147 grain/ subsonic ammunition to get the most sound reduction from the can For the .45, the 230 gr. round is already subsonic, but I only have one weapon to use it with (G21). So, with all of this in mind, any suggestions or first hand experience from those of you with suppressors? Much appreciated! Wanna kill these ads? We can help!
