FAQ
Is this pistol good for concealed carry?
It's a full-size gun, so it's better for open carry, home defense, or range use. For concealed carry, you'd want a smaller frame, but if you're okay with a larger holster and belt, it can work.
What's the difference between SA/DA and striker-fired?
SA/DA means the first shot is a heavier double-action pull (longer, heavier trigger) and subsequent shots are lighter single-action. Striker-fired guns have a consistent trigger pull every time. The TH45 gives you that extra safety margin with the DA first pull.
Does it come with a case?
Yes, it ships in a hard plastic case with two magazines, a cable lock, and the interchangeable backstraps.
Can I mount a red dot?
No, the slide is not cut for a red dot. You'd need to send it to a gunsmith for milling or use a dovetail mount if you want an optic.
Is it reliable with hollow points?
In my experience and from what I've heard from other shooters, the TH45 feeds most hollow point ammo reliably. However, always test a box of your chosen defensive load to be sure.
