Glock 30 w/10mm conversion bbl or Glock 29?

[cadjak]

I am trying to decide whether to buy a Glock 30 .45acp and get a 10mm conversion barrel or just buy a dedicated, 10mm Glock 29. I like the versatility of having the 2 calibers, and a 10mm conversion barrel will handle the Double Tap 230gr. WFNGC Hardcast, better than the stock G29 barrel. I do have a use for that load. I'm new to Glocks I'm not sure how well I'm thinking this through. Any advice?
Thanks,

If reliability is a concern, stick with a dedicated platform. I'd never use a conversion anything for self defense.

if you get the glock 29 you could get a conversion for 9x25 dillon, .40 s&w, and .357 sig.. if im not mistaken. and if i am, someone will probably correct me soon. so there you go 4 in one is better than 2
