Many smaller guns actually prefer the heavier slower bullet because it stops the gun from cycling so fast that it causes misfeeds. The lower recoil is nice too. Nothing wrong with carrying them as long as your gun cycles them reliably.
I kinda tend to agree with Wrench75. I run Hornady 147 gr XTP's in my Shield and it cycles just fine. I used the Shield as a light weight/small form factor summer EDC. I've since changed my way of EDC to a S&W 9C full time running Hornady Critical Duty 135 gr FlexLock. Going to "gift" the Shield to a family member.
While both Hornady Self Defense rounds are a "tad pricey" and can't currently be easily replaced, I figure if I have to use either, the last of worries is going to be cost or recoil.
