Hi Everyone,
First post here but i have to admit i've been learning from the forum ever since my first PCC purchase in March of this year, so it has been a long time coming. I have a 7" FM9 that i have only about 150 rds through that I really bought for my wife. The pistol had of course an AR10 spring in it with their factory buffer and the slimmest CH i've ever seen and it was a BEAR to charge. Really impossible for a 125 lb girl.
Did some research and went with the JP SCS enhanced drop in kit and a nice ambi charging handle and she can charge it fine and it made an unbelievable difference in the difficulty to charge the weapon, probably 60% better or more with the smoother SCS and wide handle. Now i am running into some issues tuning it with the spring or system being a little to light (i think???) The bolt will lock back after 1-3 rounds with Winchester 115gr ammo. Recoil feels better of course but I think the system is just too light, but i am a noob.
I can't get anything from JP or Foxtrot Mike because now i have done the dirty and crossed companies parts and neither wants to give any advice because of all the unknowns. If there is anything that i have learned from PCCs its that each is pretty unique in itself and there are tons of unknowns; between springs, bolt weights, ammo, etc. so i understand but also puzzled at the same time.
Outside of the JP SCS its a fully factory FM9, and maybe i just need to try JPs Auxilary Spring Rate kit or some quarters in the back or different ammo or all of that? JP has certainly had the opportunity to make the suggestion to buy their extra springs but they are super tight lipped and don't even want to make a list of suggestions. I've read several places where some FM pro shooters are running similar setups by using the JP SCS but again, hard to pin down details.
Thank everyone out there for what i have already found, I'm sure i can get this working, just hoping to get some experts thoughts out there?
Thanks,
Shane
