So sayeth the American Rifleman on page 82 of the current issue. Haven't they been promising this for the last 18 months..at least? For some good reasons, I can't see this happening unless they do some very specific things. First is choose the ammo it'll work with, specify which brand/bullet weight/case material it's made to shoot and not care that it won't shoot anything else. Of course, the smart move would be to choose something compatible with the largest field of competitors so people have the most options...but trying to make it shoot ANY 9mm is going to bite them in the butt...again. Remember that back in the early part of the last century they successfully made some test guns in 45 ACP for the Navy...so it can be done. But making the Pederson lock work in 45 is a heck of a lot easier than in 9mm. It's an almost straight walled case that works at fairly low pressure...and for the Navy they only had to work with ONE bullet, the 230 ball. 9mm is tapered and to an amazing degree from brand to brand. Part of this is the SAAMI vs CIP specifications...they're very close but not identical. Throw in cases with varying degrees of elasticity and thereby friction and you've got a problem. Reason is the Pederson action gets all of its' energy in that first .080" or so of blowback, and the rest of the action must be machined to allow this input to fully function it but also control battering should it be too energetic. Compare a relatively 'sticky' brass case with a steel one...and that blowback energy pulse is going to be very different. If you make it to work with one...it's likely to not work with the other or if you do it the other way around it'll be battered to death in a few thousand rounds. At least that's my take on it. Of course, the first aborted attempt to produce the R51 was also compromised by sloppy assembly and machining. Loose sights, wobbly triggers and slides that can't be racked have nothing to do with making the cartrige work with the Pederson action...that's just crappy work. But even a perfectly built gun is going to be hamstrung trying to eat any ammo you feed it. I'm hoping they get a working gun out to the public and have it tuned to work with the more common and available ammo. I'm positive that it can be made to work but is always going to be less flexible than a Browning tilting barrel and thereby more expensive to produce. The only other uses of the Pederson lock in a working gun found it more trouble than it was worth..and this was even using just one bullet weight! Good luck Remington!
