Cheapest you can find. It won't care.
Looking for suggestions to run about 100 rounds through the gun to before testing SD ammo. Any suggestions?
while i haven't picked up a Shield (yet lol) both my compact and full size MP 9's have ran perfectly on Blazer brass, Remington UMC, and Herters (Cabelas) 115 fmj.
They have been 100% flawless (2600+ rounds) and i normally pick them up in the $10-12 range max for 50 at Gander, Cabelas, and even Dicks when on sale.
OP, in my Shield research, seems some have also mentioned from an accuracy stand point that 124 grain does better for them over 115.
Perhaps grab a couple boxes of the same brand but different grain to compare for yourself to see what works best for you.
THIS. The Shield is a pretty hungry animal and not too finicky.
Although, there has been a few people on this forum that have had some failures with 115gr. It has been suggested to them to run 124.
I only run 124gr through mine. 300+ rounds of FMJ with no failures.
Please tell me where you bought the Blazer ammo. I have not seen a better price. Thanks.Buying on line is much cheaper. Just ordered Blazer ammo yesterday, brass casings, for $9.43/box of 50.
