Why This Bundle Wins for Recreational Shooters
The Rost Martin RM1C hits the sweet spot between budget pistols and premium brands. That Viridian RFX11 red dot? It’s not just thrown in – we’ve verified zero holds through 500 rounds on our Spring, TX test range. The 4″ barrel gives you better sight radius than compact models without sacrificing concealability.

I don't write reviews often but F1firearms deserves one. The Rost Martin RM1C Bundle 9mm 4" Barrel 15-Rounds w/ Viridi... is exactly what I was looking for. Good build quality, snug fit on my G17 Gen4, and the price was the best I could find after checking multiple sites. My only note would be to keep the shipping times where they are — I had it in hand within a week of ordering. Will be a repeat customer.
