Hi, I been thinking of getting a tactical 22 for a while and the few I have narrowed it down to are the S&W M&P 15-22 or the SIG522. A couple of people told me to stay away from the Colt and the AK 22’s but also suggested the Keltec SU-22 does keltec make good firearms? Is there any truth that HK is going to make a 22 also?
