They seem to be clearing everything R51 related out. Magazines for $14.99 - get em while they are hot!

I bought this Talon holster on the Remington website:

https://www.remington.com/shop/R51-Talon-OWB-Black-LH/p/16855

It was initially pretty tight but after following normal final fitment/stretching procedures it's a pretty decent holster. The thumb break as you mentioned fits over the end of the slide and not over the grip safety.

At Sportsman's Warehouse for $299

I bought a set of the black and white G10 grips and a set of the fiber optic sights. I had a hard time deciding between the F.O and Triticon units. I bought 2 magazines and a talon OWB holster last time they had a sale.

I got an email from Remington yesterday - maybe you did too? There are sights (Tritium and Fiber Optic) back on the website again, as well as a couple of different grip sets.

I have been laid up all week with the flu but still hoping to get to the range next week. I've picked up and printed some targets, and purchased two more magazines for a total of four.
The holster, much like the Bianchi 100 someone previously posted, didn't allow the pistol to fully seat due to the shape of the trigger guard. I removed the stitching that defined the trigger space and soaked a portion of the holster. Then I wrapped the pistol in saran wrap and put it in the holster.
It was pretty easy to reform the leather and now the end of the barrel matches the length of the holster and the sweat shield almost covers the entire slide. I clamped the excess and let it set overnight to dry. The next day I drilled a line of holes with my drill press so I could re-stitch the trigger guard, stiched it up and looks like it's going to work and look fine.

I'll post a picture when it's completely finished.

Grandpax12, I work for Providence Health and Services in Washington States as a Radiology Imaging Analyst/PACS Administrator. I'm a jack of many trades knowing only enough to be dangerous in any one of them and don't have any of that alphabet soup after my name :-)

Chokejug, I have never been able to warm up to Kydex although I can see it's usefulness. My favorite holster is a OWB crossdraw Bianchi Cyclone for my S&W Model 65 but that thing is way too heavy for me to carry anymore. I have a horsehide AIWB holster for my Ruger LCR with a single offset clip which is fine but I've put on some weight and it's not as comfortable as it used to be. I have a selection of leather OWB holsters that are the easiest and most comfortable to wear but harder to conceal.

I bought the R51 specifically to carry it all the time,  IWB. The cheapo Desantis IWB with loops is probably just the starter to encourage me to stay on a diet and get some practice. I have a fanny pack and a sling bag set up for carrying a firearm too that will work fine.  If the R51 turns out to be reliable enough for every day carry then I will look at spending a little more for a horsehide or hybrid holster.

My first range trip with it will be tomorrow and I have 300 rounds of FMJ and a package of 8" paper plates. I'm hoping for the best!

I looked at a bunch of holsters on line the other night while working on a big network upgrade (lots of time wasted waiting for stuff to happen).  Created a spreadsheet comparing dimensions and then collected a bunch of pictures (thanks to wikipedia). It looks to me on paper anyway (actually, on computer screen) that the Walther PPK/Sig 232 is about the closest size and shape to the R51. I also compared the Makarov, Beretta 85, and the Sig 239.

SIG P232         Remington R51
6.6"      Length      6.6"
3.6"      Barrel length   3.4"
1.2"      Width      1.0"
4.7"      Height      4.6"
4.8"      Sight radius   4.6"

So I ordered a Sig P232 sized Desantis Cozy Comfort for $40 off Amazon. If it needs a little detailing, I can always soak it and fine tune it some. If that doesn't work - well, let's just say it won't be the first holster I bought that didn't work out.

I wonder if it's a matter of the expansion characteristics of dissimilar materials (aluminum frame, steel pin) from the heat of extended shooting sessions?I have read that a HK P7 is hard to handle without gloves after 50 rounds - does the R51 frame get hot too?

There is a type of loctite - purple in color I think it is - that is specifically made for "circular part bonding". I will watch for this on mine too, thanks for the great photo.

Hello there I just picked up my new R51 from Sportsman's Warehouse in Federal Way on Saturday. I've been pretty busy this holiday weekend but hope to tear it down for a good cleaning this week, and look forward to taking it to the range and running a couple of hundred rounds through it.

I read through many (maybe even most) of the posts in this forum and found them to be very informative. Thank you for taking the time to post - they were instrumental in convincing me to go ahead with this purchase.

I ordered a couple of additional magazines from the Remington website today (used an on line coupon for 20% off) and have been looking at IWB holsters. I'm pretty confident that the difficulties that some of you have had with the Gen 2 have been or will soon be resolved. The rebate makes the price very attractive and worth the risk, in my opinion. It's a beautiful piece with excellent ergonomics and a perfect form factor for IWB carry.

I also like the fact that Remington is thinking outside the box with this product, and am happy to be supporting American workers and business.

Best Regards and Stay Safe.
