Both are nice additions
I am not going to write reviews for both of them but the slide stop and safeties are both nice additions to the PMR-30. Not much to say they are just aluminum upgrades that do what they are suppose to.
Safety selecters.
Really happy with this upgrade. The larger safety switch is much easier to use for my big thumbs. They are larger and more tactile than the stock switches and it has a much more distinctive/positive click when moving it from safe to fire and back.
Good buy!
Found that with younger shooters the stock parts are not ergonomically suited for them. Switched them out and now I have to “fight” for my turn with my son.
Cannot Rate this at this time
I boought this as I recenly lost the tip of my thumb. I thought an extended lever would make operation easier. I called Keltec and found out that any parts install that required disassembly beyond firld stripping would void the warranty unless done by Kel-tec or an approved business such as MCARBO. Since I reside within reasonable driving distance of Kel-Tec, I will make the trip to them for and install to keep my warranty intact.
Nice Quality But..
This thumb safety lever is very nice quality and not too bulky, just prominent enough to be more effective. I am right handed and my PMR30 is not used for tactical purposes so I installed the left side lever only and left the factory low profile right side lever alone. The one area I would suggest for improvement is the unnecessary (imho) slope on the underside/bottom surface of the lever's thumb shelf. Even with my short fingers/thumb, I have to slightly shift my grip back off of the pistol's back-strap to engage the safety upward with my thumb knuckle, and a more perpendicular surface on the underside would probably help to make this operation easier. (ie, Using same logic as MCarbo used on their PMR30 Slide Stop replacement tab) Thanks again for your great products.

KEL-TEC PMR 30 Extended Aluminum Safety Selector
KEL-TEC PMR-30 Extended Aluminum Safety Selector. They are surface area positive and very ergonomically comfortable. The serrated width of the safety selector does not impede the thumb reach to the last purchase I made of the also surface area positive KEL-TEC PMR 30 aluminum slide stop! Having mirror image left and right selectors is a great.
$50 is way to high!

Any plans of just offering just a left or just a right side safety? If bought it I’d only use the left side being right handed

At this time, we do not offer a left-only or right-only selector kit - you can install just one side of the selector from the current kit — it will still function reliably as long as the selector shaft is properly secured.
Same question, I would like to just use the right side for a PMR 30 and a CMR 30 as I'm left handed.

Will these fit the Keltec P17? If not, are there plans to make an aluminum safety for the P17?
February 14, 2023 2:36 PM
No it will not. The P17 has a completely different firing and safety system. At this time we are looking at the possibility of in the future.
So does anyone know if these interfere with the farrowtech collapsible brace? Thanks
We at MCARBO have not tested them with that brace. All testing was done with stock firearms so we can not say if that brace and safety selector will make contact or not. It is possible someone in the Forums have tried that combo, i would check there to see if it has been mentioned.
