I picked up my Shield last Thursday. 9mm w/o safety for $400 out the door from my favorite local shop. Got to the range yesterday an put 100 rounds through it. I really like this little shooter.
Started with WWB 115 gr FMJs and was quickly shooting fist-sized groups from about 8 yards.
It didn't like the Blazer Brass 115 gr FMJs I brought along. The groups moved up and left and opened up into more of a pattern than a group.
I've had pretty good results with Blazer Brass 40cal in my CZ75; but the little Shield does not like the 9mm version at all.
When I get a few more hundred rounds through it I'm going to start experimenting with defensive ammunition. Then I will look for a cheaper range alternative that mimics the accuracy and POI of the carry ammo.
I need to find a good IWB holster and twice weekly range trips and about 1000 rounds of ammo to "get aquainted with each other."
Then, if all is good, it becomes my EDC.
