More gun is never a bad thing until it reaches the point that you have so much gun you leave it at home.
Well put.
A friend of mine..a Gentleman in his 80's..recently asked for my help in choosing a new EDC firearm.
He had a nice S&W M36 .38spc that he carried since the 1970's. It was a good pistol and he could be quite effective with it but age had degraded his eyesight which led to him having trouble acquiring the front sight. He was a very good shot, had experience on the US Navy Pistol Team, and combat experience in Vietnam. His stance and shooting techniques very much reflected the 1960's and 1970's. The pistol was normally kept in the glove compartment of his vehicle.
I let him shoot my P365 and he was very impressed with the pistol and its capability. With the night sights standard, it turned out be easy for him to see. Additionally I was able to demonstrate some shooting drills for multiple targets and various magazine changes (tactical and emergency).
He ended up purchasing a P365, holster, magazine holder, and two 12 round magazines. He has since routinely practiced every morning drawing, grip, and stance adopting to a modern style.
He carries the pistol on his person in such a manner that he can get to it whether driving, sitting, or walking. Several times he has remarked how much better able to defend himself and more capable a defense he is now able to put forth compared to the Model 36.
One of the few who able to adapt to new tricks after a lifetime of doing very well with his older techniques.
