However, when purchasing guns there are so many choices these days, personal experience is my way of narrowing my selection down. Everyone I have talked to has told me to just put a few more hundred rounds through it and it will smooth out, but with ammo availability and pricing, I can't justify spending my time and money hoping it becomes reliable.
That is all you can really do... Ive owned many guns that worked but hated and loved but didnt work... It is what it is. I will agree with you though, 1500rd and it should already be perfect and shouldnt need more "breaking in" something is wrong or the springs prematurely failed. I dont make excuses for any gun no matter the name on the slide..
Good Luck
