Pretty much with any gun. I can't tell my two 66s apart or my two 36s. All my Glocks look the same as well as both my HK USP. All my 3rd gen S&W look the same too! Hard to get excited about any of them. Seen one, seen them all.
No interest in a single stack Glock or single stack anything really but I can see how they will sell
Unless your sporting rubber on those 66's each pair of wood stocks should have individual character .Something that is missing from the cookie cutter poly guns of today.Years ago a shooter could pick his gun from a table full of identicle models.
