I just completed my 200+ round break in of my CM9. Happy to report, out of 250 rounds, 4 different ammo types/brands, I only had one FTF, which occurred on the 2nd round of Winchester White Box. Has been perfect since that second round. Break in of 200 rounds was WWB. Then I tested Hornady Critical Defense 115g, Winchester "D" 124gr defend ammo, and Federal 124g hydroshock. All performed perfect and were accurate. Now, I just need to decide which ammo to carry. She's ready to go.

Very glad to see a lot of HST love around here for use in the CM9/PM9. I am a very newly minted PM9 owner and have some boxes of HST in both 124 and 147 grain standard pressure. (Yes, I paid through the nose for the 147 but VERY glad to have it).
My thoughts are that the 124 will zip a tad better to aid in expansion from the 3.1" barrel of my PM9, and then use the 147 in my Beretta PX4 Storm Compact with a 3.27" barrel. Make sense?
