There are just too many good pistols to select from! Only recently upon approaching retirement did I take up shooting. I had never shot a handgun and decided to go with a 9mm Shield because it concealed so well. As a novice at the time, I was unaware that it is more difficult to learn the fundamentals on a subcompact. Well in order to keep the story short, I am finally shooting well with the Shield (and that is only for my standards alone!). So, I have now decided to add on a standard/compact size pistol. Originally, I was going for the Glock which has been called the AK-47 of pistols. As far as I can see Glock has established the standard for striker carry pistols. As I see it, the Glock is an excellent pistol the G19 is accurate, reliable and easy to shoot whether you be either an expert or beginner. But when you have those additional purchase options of some many good striker fire pistols not limited to: Sig Sauer's P320, Heckler & Koch VP9 and the Walther PPQ (I left out some other very good brands), the decision becomes more difficult. All four are excellent pistols and to tell you the truth I don't believe I could go wrong by selecting any one of these models. However in this case, I only looking to buy one darn standard/compact size striker fire pistol. I certainly will not be buying all four pistols. However, I'm reminded of the feeling of buyer's regret. No pistol is perfect. Each one comes with it's own individual pros and cons. However the cons of whatever pistol I purchase will lead to equal buyer's regret. One of these days I will have to bite the bullet. As quiet as it is kept, how lucky I am to have these options!
