Hello I have been out shooting the springfield XDm 45 4.5 and my glock 21sf. These two guns are excellent,Accurate and very dependable in my opinion. In the last two days I have put 900 rds thru each. I carry a sig p220 or a 1911 but after spending the last two days shooting the glock and the XDM it is very tempting to reconsider. As far as in your opinion , dependability and durability which would take the lead? BTW I know this is a glock forum but try to lookpast this with your replies. Thanks I'm not talking about feel or accuracy just Dependability and durability.
