500 rds through my XDs with no problems of any kinds.

Ammo used to date.......

150 Winchester Ranger 230gr
75 185 +P Remington Golden Sabre
100 rds 230gr American Eagle
50 rds of Federal 230gr Hydro Shok
50 rds of Cor-Bon Power Ball
75 rds of 185 Hornady FTX

Out of all the ammo fired,the FTX is the most accurate and pleasant to shoot.
Worst accuracy came from the Cor-Bon,

As far as the Shield,the gun shop I work in has only received 4 since their introduction

A bird in the hand,is worth 2 in the bush.
I"ll stick with the XDs until I get a chance to shoot a Shield.
