As I recall, FN Herstal was the one of the first manufacturers to make full ambidextrous controls for there pistols. The FNX, FNS, and FNP series of pistols all have fully ambidextrous controls: Slide Stop, Magazine Release, and safety (if equipped).
All these are now available on the new Ruger American Pistol. This looks to be a great pistol for all folks. Chambered for both 9mm and .45 ACP, each pistol is available in the standard 4.2″ duty size or the 3.55″ compact. You also have a choice with the pro models offering no safety catch, or the models with an ambidextrous thumb safety catch.
Speaking of compact, these feature a narrow grip width of 1.19″across all models. For personal fit, they come with 3 different backstraps, to fit most hand sizes. Other features are the Novak LoMount Carry 3 dot sights and a Picatinny rail.
I like the more aggressive slide serrations over the SR series, but may miss the lack of the striker cocked indicator. And for whatever reason, Ruger still won’t make .45 magazine hold more than 10 rounds.
Some will be disappointed that there is no .40SW version, however, I feel they really missed the boat by not adding a threaded barrel version. Suppressors are making a lot of progress in the shooting world, and it’s just a pain in the ass to buy a new pistol, only having to spend a few hundred more on a threaded drop in barrel if they are to be found.
The most prolific pistol in the world, The Glock, can now be easily handled by lefties thanks to the MARS from Rainier Arms. This drop in magazine catch will take your right handed only release, and not just convert it to left handed friendly, but also make it fully ambidextrous.
The Magazine Advanced Release System is a drop in solution that allows full ambi control with no gunsmithing, a first for lefties that I am aware of. Not made of plastic, but 6061 aluminum with type III hard coat, this should be a durable addition to the durable Glock.
Looks like I will need to get a Glock now.
I’m loving the ambi mag release on 2 of my billet lowers, the CMT TAC, and the San Tan Tactical. Both put the button in the right spot and both are easily manipulated. But I’ve got a few forged lowers with no accommodations for the left of hand. There are few good ambi catch out there:
I skipped the Norgon, because it looked like there is little mechanical advantage to the system, and would require more effort use with one finger. I also passed on the KAC, since it seemed to busy, and likely to catch on something.
I put the Troy ambi on my Aero lower. And it does just what you want it to do. It’s out of the way, but accessible. There isn’t a lot of extra effort needed to drop the magazine, and it doesn’t look too prone to accidental drops either. It’s lower profile than the HVA, and doesn’t get in the way of a standard bolt catch. The only thing problem I can see is that it may mark, or start digging into your lower for it’s leverage.
I put the HVA AMR on my Stag lower. It’s bulkier than the Troy, and it is quite close to the bolt catch. It has a very smooth action, and doesn’t require too much effort to drop the magazine. If you’re smart, and already replaced the bolt catch with Forward Controls ABC/R, then you’re also in luck. While it sits close to the bolt catch, it’s not in the way, and easily accessible.
It’s tough to pick between these 2 bolt catch’s, and I haven’t decided which one fits my hand best, but both work well enough to stay on both hosts.
I’ve been shooting a left handed Stag AR-15 for a few years now, and wanted to build a new true left-handed rifle from the lower up. The Stag is great, but it still rides on a standard right handed, non-ambidextrous lower. Thanks to the fine folks at CMT-TAC, the’ve come to the rescue with a great full ambi lower.
The UHP15A lower has everything you’d expect for a great billet lower:
- Full Ambi controls: Bolt catch and mag release:
- Threaded bolt catch pin (no roll pin installation needed)
- Integrated oversize trigger guard
- Compatible markings for 45° safety selector
- And generally great manufacturing
The Lower Controls
First we’ll start out with the ambi mag release. It’s gated to help prevent unwanted mag drops, and is easily accessed and manipulated with your left index finger when holding left handed. The back side is conjured to the trigger guard, and has a bit of a point, so It may snag, but that hasn’t happened to me yet, as I’ve only bench shot this rifle. It’s also set up so you can use a standard LPK mag release. No special parts are needed to build up this rifle.
The ambi bolt release on the side works just as well. While operating left handed, I like to close the bolt with my right thumb, it just feels natural that way. It’s also situated behind the dust cover if you have a standard wrong sided upper on the the rifle. If you’re holding the rifle right handed, and have an extraordinarily strong index finger, you could close the bolt. If not, two fingers will work.
These controls are the main reason to pick up this lower. The rest of the lower is a well made billet lower. The maxwell is flared, the integrated trigger guard will let you wear gloves, and it fits like a glove with my upper.
The only improvement I would add, is a threaded rear take down detent hole. My Aero Precision forged lower has this, and it’s great for the build. Even better when you decide to take off your buffer tube and forget the dentent and spring are still behind the end plate.
Now that you’ve got this lower in hand, you can only make it better better by putting a UPUR-1LH atop this.
