I would suggest you buy no more than 1 box of each type/weight round for your pistol, then test fire it, trying a few mags of each type,to see which type your pistol "likes".. all pistols can/may/will be different.
Example 1 box winchester 115 gr rn FMJ
1 box Remington 115 gr rn FMJ
1 box Remington 124 gr rn FMJ
1 box Federal 124gr rn FMJ
1 box winchester 147gr rn FMJ
pistol "likes".. = feeds & ejects without problems &
most importantly, shoots the tightest groups =most accurate for your gun.
You should find, over time , what ammo your pistol likes ,
then buy mass quantities of that ammo! Have fun..& Good Luck..Joepistol..
