I have fairly large hands and use a Geppert Convex with material removed from the rear of the shoe to make it even shorter.
If possible, try different shapes and lengths before buying what not be right for you.
If you don’t care about how it looks, there’s more than enough material on the Dawson base pads to remove the upper front corners and not loose functionality.
CKARMS with Taccom ULW barrel is hard to beat, especially for steel. It comes with a mil-spec trigger, which have been proven to be pretty nice, but that allows you to choose the trigger “you” want rather than what the builder thinks you should have.
With 4 rounds in my MBX mags, the follower is visible through the mag catch slot. Seems likely that the follower is getting caught on either the mag catch slot or the mag catch, itself.
Remove spring and follower from mag and insert into gun with slide removed. The mag catch should not be protruding into the magazine.
