Misfire with the stronger striker spring?
Can you get Power Pistol powder? It is the "new unique" for the higher pressure calibers. Titegroup is very forgiving. You might be on to something. Quicker peek pressures rates might be the answer. You will not get maximum velocities but it might be better for the XDm. Might surprise you in the short barrel also.
I like this thread. We are all learning here.
With the faster powders, might want to look at Hard cast.
