It was indeed. I never see them mentioned by model number with them being so rare. One in 500 would be pretty interesting but it would have to be chonky.

From what I've seen, the .375 Ruger has actually developed a bit of a following.

CZ used to do LH safari rifles, but only in .375 H&H, none of the big boys.  Oddly, Numrich has LH Winchester Safari stocks available, but I've never seen a complete rifle.  I'm tempted to buy one and then keep an eye open for a lefty model 70 for a rebarrel.  Montana used to make lefty rifles in .458, but they were really light and not what I was looking for in terms of features.  I could always get a #1, but the idea of a single shot in a dangerous game caliber really doesn't do it for me either.  Until I stumble into a lefty .458 that I like I'll just make do with my .375 Rugers.

Never thought it would happen, but I may be going to Africa in a few years.  It won't be for dangerous game though, so I'll be taking a .300 or .375.  Which one depends on what I decide to hunt.  Definitely no use for a .458 for anything I'd hunt there.

How about a future Pistol caliber Lever Action rifle in .30 Carbine?

The thought has a merit. The bullets are always flat-nosed in 30SC, so they are compatible with tube magazines. Could really be something sweet, if made with a good quality.

I had a No. 1 in 416 Rem Mag and 458 Lott.  They're fun guns if you want a big safari caliber just to show off, but I agree that I wouldn't want one for dangerous game.  I could reload them fast but not as fast as a bolt.  The Lott in the No. 1 also had brutal recoil, like way worse than my CZ 550 in 458 Lott.

I've heard that the No. 1's tend to be big kickers in the larger calibers, which is another reason I've avoided buying one.  My .375's (an African and an Alaskan, both pre-muzzle brake) aren't too bad in the recoil department, but any .458 will probably be a pretty significant step up, so I'd prefer to avoid models that are known to kick like mules.

I'd love either a PC Carbine or Mini in 357.  10 round mags would be fine and an adjustable gas block if I'm wishing

OR

A LCRx with a 3" barrel in 9mm

Either one with a  proprietary Ruger magazine and include a mag adapter for Desert Eagle mags.

Have just begun to look into .45 ACP carbines, but initial research seems to show some viable alternatives out there.

If Ruger won't make what I want, then my money will go elsewhere.

I would buy a Glock mag .45acp PC Carbine in a heartbeat if Ruger would make it.

I could get on board

PC carbine 45acp

The "micro-14/m57 carbine" a 10/22 form factor rifle in 5.7x28 that takes their 57 handgun mags.

The Hawkeye African is a fantastic rifle.  I've got both a 338 win mag and 6.5x55.  I'd like to see expanded caliber selection, but really, just increased production of the Hawkeye line.  They're impossible to find.

And .30 Carbine as well!
