How are you doing with others, as a comparison ?
We all have off days, mine tend to run to weeks, and some times one will have a weapon that just does not feel right. I have a SIG 239 that I shoot pretty good, for me, with the .357 Sig barrel but I do not do as well with the same gun with the .40 barrel.
We are strange people wandering in a strange and foreign place !!!
