I have a long list of firearm platforms that are very popular that I just have no attraction for...
1. The venerable AK47/SKS. I hate stamped metal guns and the commie guns are crude and offensive to me. I shot an AK for the first time last summer and it just cemented my dislike of them.
2. Single-shot rifles from H&R. Crude. My brother had one in .204 Ruger and it was inaccurate and ugly.
3. Pretty much every semi-auto from Ruger. Again, the fit and finish is subpar and the polymer feels cheaper than that used on other semi-auto pistols; even my $199 Taurus G2c. My first carry gun was a Ruger P90 .45 acp and it offended me with it's enormous clunkiness, though it was reliable and reasonably accurate, I just never warmed up to it.
4. Any gun with the words "Grip Zone" on them. I love my XDS, but SA seems to turn me off with a lot of their other offerings.
5. CZ guns. I don't like religious cults and I don't like gun cults. I don't like the below average fit and finish and the lettering on the slide looks like it was done by Airsoft.
6. Early Glocks. Ugly and feel funny. Gen 3 and later? Love them! You want to pay $2000 or more for a rare early Glock? Fine. I have no interest.
7. 1911s. Love the looks and how they feel. Navy issued me one and I shot it well. I just can't get over their weight and low capacity and finicky reliability. I love single-action pistols, but I would never use one as a carry gun. Weight/size/capacity makes the 1911 a poor choice for self-defense.
8. Hi-Points. I get that they work and are appropriately priced. The moped/fat-chick of the gun world. Fun to ride until your friends see you.
9. HKs. I worked for an ammo company that had every flavor of high-end weapon on the market and got to play with them. My first thought upon handling an HK USP was that it was over-hyped, clunky, complicated, and just not my thing.
10. Sig semi-autos. Heavy, thick, and overpriced. Ironic that my favorite gun of all time is currently my Sig P365. Wonderful little pistol. Can't stand it's big brothers.
There you go. Generally, I like guns with above average fit and finish and simpler controls. I grew up in my dad's gun shop where there were quite a few high-end custom rifles, some approaching six figures. So my tolerance for crude weapons is pretty low.
