The argument about the relative merits of these two pistols has gone on for years. Let’s take a look at the technical parameters and then compare the intangibles. The guns are roughly similar in size, with PMR-30 just a little shorter and slimmer. Both have manual thumb safety. FN5-7 magazines are easier to load. PMR-30 has less felt recoil and crisper trigger.
5.7×28 is obviously more energetic from a pistol than .22 WMR. Due to the high velocity, 27-grain frangible actually penetrates lower level vests, though its effect past the vest is minimal. Designed to break up on backstops, the leadless hollow point actually cannot penetrate a full soda can all the way. Most other 5.7 loads are also designed for fragmentation, if a bit less drastically. Six to seven inches of penetration isn’t unusual. SS190 and Elite Ammunition defensive loads are the exceptions. By contrast, pretty much all .22 WMR loads are either designed for penetration or act that way due to the lower velocity achieved from pistol. So the wound channels are more narrow but much deeper, from 14 inches with the low-powered Dynapoint to 20+ inches with Maxi-Mags and other 40-grain loads.
To this day, I know only one person who owns both of these pistols. Everyone else made a choice for one or the other…and most have strong feelings as to the reasons for the selection. Do you own one of these guns? If so, why did you pick it over the other?
