I own a GordonTech SLR100H, 2 Polish PMKMS underfolders and a stainless Mini Thirty.
The Mini Thirty shoots on par with the best that I can do with any of my AKs. All of them do best when using good brass cased ammo. I believe the accuracy of all of them could also be improved with either better iron sights or good optics. But, these rifles are what they are and I'm OK with that. Actually I'm completely satisfied with their accuracy just the way they are, but that's me. I like the much cheaper steel cased ammo and that is what I feed them. It all depends on what type of accuracy you will accept. I am alright with the issue sights on the AKs, but I did upgrade the Mini Thirty rear sight to an Ashley peep sight. It is not adjustable for windage and elevation without a screw driver (little tiny screw driver with little tiny screws). Not something that can be adjusted in a hurry in the field. What you can do with it quickly is unscrew the small aperture, which leaves you with a very large aperture. This works well for close range quick shots. The stock Ruger rear sight broke shortly after I owned the rifle. It was a bad design and I would not put another Ruger sight of the same
design on the rifle even if it were free under warranty. Now to the magazines. Ak mags are built like tanks and once tested can be relied on with great confidence. The Mini Thirty is another story. It's totally reliable with the factory 5 round mags. I have probably tried a half dozen USA mags when I first got the rifle years ago. All except for one stainless twenty rounder are junk. That stainless mag has always worked flawlessly. The rest are paper weights. I'm sure some people have had better luck in this area, but it is hit or miss at best with most high cap mags. Years ago, I was also lucky enough to come across some Thermold expandable 30-45 round Mini Thirty mags and bought several of them when the price was semi realistic, like $30 a piece (still high in comparison with AK mags). These mags are totally reliable and durable. I have a sturdy side folding stock on my Mini and also have a synthetic sporter stock. With the side folding stock, the peep sight upgrade and the Thermolds, the Mini is a handy, reliable and an acceptably accurate rifle for me. If I what to hunt with it, I can switch back to the synthetic sporter stock, throw a scope on it and it's good to go. I wouldn't sell my Mini, but then again I don't sell many firearms. If I wanted an assault weapon and I had to either keep a stock Mini Thirty to fill that role or trade it for a good AK, I would trade it. The AK was built for that role, the Mini Thirty was not. The way my Mini is set up, it is reliable, durable and it could fill the assault weapon role nicely, but it took mag experimentation and add ons, all costing money that could otherwise be spent on ammo and practice with an AK. The stock Mini Thirty trigger is probably a little better than the AKs. It's heavy, but smooth. Another thing to consider, is that Ruger spare parts are just not available. It's a trip back to Ruger to get it fixed, but the Mini is also a very sturdy weapon and doesn't have many parts go down, although I'm sure it does happen. For what it's worth, new shooters who I've taken to the range shoot the Mini Thirty much better than they shoot the AKs initially. I have not seen groups get rediculously larger when my Mini Thirty gets hot. Larger, yes, but not anything terrible. I have heard that the stainless models are not as affected by that. Probably more info than you wanted or needed, but there it is. Good luck on your dicision.
