Round ball, I had a Glock Model 26 and 27.I still have the 27 but traded the 26 in last year.Both are quite accurate for their size.I didn' t shoot either very much but was very satisfied with their performance. The only reason I got rid of the M-26, I' m not much on the 9mm.I orginally wanted a M-27 but they were few and far between them when they first came out. About a year later I got my M-27.The Baby Glock' s are easy to conceal and light to carry.I would recommend one completely.A Big Gun in a tiny package.
Ruger Redhawk
