Not a fan of "universal fit" holsters. Especially for a concealment holster. Kinda like carrying in a bag! But, if that's what you want looks like the size 2 might work. They also make a kydex IWB for about $5 more. They don't list the 30 but the one for the 19 should work fine. If you'd like to get into a leather one, and price is the deal breaker. You might consider a Don Hume. I have one for a 1911 that was around $20 as I recall.
