How would SSCY compare as a good budget 9mm?
They aren’t bad... I’d call them economical. Is it a match pistol? Hell, no. But they do work. Shoot some rounds through it, if you have issues... they do have a decent warranty (lifetime, shy of abuse; think you just cover shipping to them). If you buy something that doesn’t have a normal track record (Glock, Beretta, SIG, etc), put a good amount of rounds through it to confirm it works. Depending on what you are looking to do with it, will point out that the SCCY pistols don’t have a rail for a light. If home defense, I’d prefer a rail mounted light... but something that is your decision. A little more input would help us see if there is any reason a SCCY wouldn’t work for you.
Another option, check gun shows or used pistols. Can find police trade ins for a decent price, usually just some finish wear. Might even get you in the ballpark of those new... and if something like a Glock, cheaper accessories/parts/magazines. Those are just a handful of costs that most people don’t consider. Paying a couple dollars more might get you into a platform where magazines are plentiful and cheap. I’m sure you can find accessories, but look up holster options between those and any common Glock model...
Not trying to sway you away from SCCY... but rather you look at the entire purchase process. You might thing it is just a gun... but you do tend to spend a lot after the original purchase. When I went into 10mm, I figured a few dollars more than a Glock 20, and I’ll have a S&W 1006... a solid, nine-shot, chunk of stainless steel. When I got into it, magazines were in the $40 range. Jumped up to $60 by the time I was done buying them... they go for $100 today. Glock 20 magazines... $22 for new 15 rounders, all day long. I’m not too up on SCCY pistols, but definitely look into what magazines go for, and if they are easily acquired.
