Hello, I recently bought a 14 no dash with a 8 3/8 barrel.I am not sure if i need to consider different ammo than what i use in my model 19s. I currently use 130 grain FMJ made by american eagle. I have found no problems with my 17 no dash 8 3/8 using standard velocity .but thats rimfire of course.I shoot just for fun but would like accuracy.Gun is in like new condition and not broken in yet....Thanks
