Anyone have any experience with these?
Just be careful with the SERPA's. I got rid of the chances of me doing this by stuffing a foam earplug under the button to disable it. In stressful situations people tend to press the button with the tip of their finger instead of the side of their finger, so when the gun is out of the holster, your finger goes directly into the trigger guard and BOOM.
As to the SA XD(M) system in general, I found t to be one of, if not, the, current best op system in a pistol. I"d happily crry one into battle; it's a far cry in terms of functionality and ergonomics from teh Canadian Inglis-built P-35 Browning/FN Hi-Power I carried up there!I have an XD45 Compact and can also provide positive feedback for it. I mostly keep a full size, sleeved magazine in the gun because it's not my primary carry pistol. However, it shoots just fine for me with the 10-rd magazines; recoil is not an issue for me.
The gun is very reliable. I bought mine a few weeks before attending a training course but didn't have a chance to shoot it before the class. So the first 900+ rounds through the gun were at the 3-day course with no cleaning and no malfunctions.
My only gripe about the gun is the long, mushy factory trigger pull. I had a Springer Precision "Combat Carry" trigger job done, so my XD45 now has the trigger function I think it should have had straight from the factory. (It's still not close to the factory trigger on my Kimber Compact CDP II. Different designs - apples & oranges, I know...)
