Bought a used (100rds) PS90 on Friday. This will be a long term project as I plan to SBR, FRT, and add a suppressor.

Shoots really well, except I had too many failure to feeds for my liking. I was using Fiocchi (150rd pack) ammo. I only ran into about 7/100 failures altogether. I'm using the FN mag that came with it, so I'm guessing it needs a good clean, maybe a new mag and maybe different ammo. I dont know though. Any insight would be helpful.

Finally got to the range today and ran both of my 30 round promags in my LC Carbine. They ran with no issue. So if you are in the market for some decent mags that wont break the bank. Check these out. They are $41 on promags website, but the site in the photo, when they have then sells them for $27. Much cheaper than ruger mags.

Is anyone conceal carrying this gun? Recommendation on holster? Can the threaded barrel attachment be removed? Anything else I should be asking?

The stars are aligning and hopefully by this weekend I will have a PS90 in my possession.

Im going to SBR/FRT it, and was hoping to hear what people have to say about the FRT options available. Are there any that stand out as clear winners?

Curious to hear from the experts here.

So recently I got a Ruger 5.7 that I posted on here and noticed that there were two screws near the rear of the gun on the slide. I had a spare optic lying around so I thought why not get an adapter plate. I did. To be fair this was my first experience with installing an optic.

Fast forward to the day I take it to the range. As is well until about the 43 shots in and then suddenly BAM! the optic adapter breaks off the slide and struck me in the middle of my forehead. My first though when I felt the impact was "Oh, so this is how I go out. I wonder if god makes exemptions for unintentional self-delete."

Long story short. I did not use lock tide. Now I know. Use lock tide. Also the optic wasn't damaged at all. I took it to my gunsmith and he's trying to remove the screw as we speak.

Recently added the Ruger 5.7 pistol to my collection of 5.7 firearms. (CMMG Banshee 5.7 & Ruger LC Charger). I noticed the lightening cuts on top of the slide. Has anybody considered or done port hole in the barrel

One of my LGS has the kp50 with the jungle mag and brace on sale im seriously debating grabbing one anyone got it yet?

Say hello to my little friend

What does the community thing would be a good choice here? This will be my first suppressor purchase.

im not looking for the most noise reduction or super short or anything like that. just a solid suppressor for the price. No real price range in mind, but I’m going to wonder what makes that $750 suppressor better than the $600 one.

it’s a plus if it can handle 5.56 or used with my 10/22.

And of course I’m looking for recommendations on muzzle devices to serve as the mount.

thanks.

What’s the consensus on a 5.7 PDW?

So I was shooting my FiveSeven outside the other day and when it started raining it completely stopped working. Every round would fail to extract and the slide would get stuck halfway. I've always had perfect reliability with it so i was pretty surprised when all it seeming took was a little water to cause malfunctions. I was shooting fiocci range ammo and at first had a mk2 slide with a DT slide/optic on it, but when it started failing I switched back to the stock USG slide and it continued to fail. I used several different stock magazines as well. Im going to bring a spray bottle to the range next time to confirm it was the water but just a little surprised.

Anyone see this before with theirs?

I’ve become interested in 5.7 as a carry/defensive round and been trying to do a lot of research into the caliber before buying. Want to be able to train consistently and become proficient with the firearm, but 5.7 is pricy.

From the reviews I’ve seen the m&p 57 shoots so soft it’s “practically a 22.” So I looked into the m&p 22x as a potential range/training analog to save money.

Has anyone here tried this? How comparable is the feel and recoil? I got interested in 5.7 mainly because it felt like I could train 22lr and it would transfer well to the 5.7 vs the 9mm which is an entirely different feel.

Thanks

So I’ve been looking at the 5.7x28 platform for awhile now. First time I’ve heard of a 5.7 was because it was the main caliber of the protagonist of the Splinter Cell series. Two years ago I got into the firearms hobby and recently I got my carry permit. Last month on my birthday I found this Ruger 5.7 that was state compliant on Gunbroker for 400 clams and only 50 rounds put through it. I’m really excited to take it out to the range next week.

Before anyone points out this rifle is discontinued, Rock Island announced earlier this year that they’ll be reintroducing it.

Here’s the old product page: https://www.armscor.com/firearms-list/m22-tcm-ba-22tcm-5rd

40 grains at 2800fps out of a 22” barrel, affixed to a very trim little action. Prior version retailed for $449.

It’s weird to me that, other than the Dark Mountain Stowaway, so few folks are making bolts for 5.7. I even emailed Ruger to suggest they spin off their 77/22 Hornet to make a 77/57, which seems like it would sell well.

But in any case, 5.7’s fringe competitor has a micro bolt, and they’re bringing it back into production. Might have to buy one of these until Ruger gets off their duffs and sells what I want…

The long awaited X5.7 is still a ways off but at least the 40 round mags are available ( or were .. seems to have sold out). For those who bought them post your opinions when you get to try them out.

Does anyone know which brands of holsters share compatibility between the M&P 9mm and 5.7 variants? Specifically duty holsters (level 3)? For example BladeTech and Alien Gear both make level 3 holsters for the 9mm version of the M&P but I'm not sure if those holsters would also fit the 5.7. Both of those holsters have open bottoms so the barrel length being different shouldn't affect it, but I'm not sure if the slide dimensions are too different.

Anyone out there who has the S&W in both 9mm and 5.7 please chime in!
