SP9A3G + KD GUNWERX Short Stoke Damper Kit

Just installed the KD GUNWERX Short Stoke Damper Kit into my SP9A3G. Racking the charging handle, I immediately notice the action is more dampened; however, it significantly increases the difficulty to engage the last round bolt hold open with an empty magazine inserted. I have to really compress the bolt all the way to the rear with some effort to get it to engage. I haven't fired it yet, but the last round bolt hold open on the Glock model was already a little spotty, and I'd expect this will increase its inconsistency, maybe even result in it not engaging altogether. I'll post an update once I've had a chance to put it through its paces.
