For the sake of Pete!
Honest honorable law abiding people have managed to defend themselves with guns without any special "training" for decades! It is only recently when some people have discovered there is money to be made with "training" that there has been a focus on.... you guessed it... "training".
What did people do back in the old days when there wasn't any uber tactical super duper experts offering "training"? Well....law abiding folks managed to defend themselves with their guns ... without paying big bucks to self appointed "experts" who say that "training" is necessary.
Sure "training" has value in preparing people to respond more effectively for the time when they need to defend themselves... but History itself shows that people somehow manage to do it all on their own without training anyway. Perhaps not as well as if they did have the training yet they still managed without it.
Let us not fall into the latest BS that "training" is suddenly something that is "needed" in order to be able to exercise the right to keep and bear arms.. because I fear all this talk about "training" is laying the groundwork for exactly that... a requirement for a certain level of "training" to qualify for the right to keep and bear arms.
In the "old west" days, people who wanted to become proficient with firearms, practiced....and practiced, and practiced, and practiced some more.
If you've ever seen the old western movie, "Warlock," with Henry Fonda, you might remember a scene, where he explains to the town council that hired him, why he works as a dealer in his friend's saloon. And he mentions that the $400.00 they pay him each month doesn't even cover the cost of the ammunition he uses up in practice.
Back in that time, the typical salary for a lawman was about $150.00 to $200.00 a month. And we'd kill for the ammo prices they had then.
My point is, if you're like me, you practice as much as you can. You practice your marksmanship at the range. But, considering most public ranges don't allow drawing from the holster, you practice your drawing technique at home. Preferably with a practice weapon, or at the very least, an unloaded firearm. If you don't, you might find your reflexes wanting in a real SHTF situation. So, practice, practice, and practice some more.
