I have never had a wheel gun misfire on me. A jam is much more common in a semi-auto than any functionally sound wheel gun. I agree Glocks are extremely reliable, but so are revolvers. If your revolver does not fire, it is probably poor quality ammunition or it is disrepair. I have NEVER had a wheel gun fail to fire. Maybe it is only me, but this is MY opinion and experiences... Truthfully, I would rather carry a 1911 govt. model than my .38spl, based on potency, but that is because I believe in the .45ACP. I have also never had a failure with my 1911 that was not related to my underpowered "test" reloads.
Also, the Makarov, in my opinion, is a very reliable, concealable and fairly potent weapon. I will gladly carry one and not feel under-gunned.
