For me:
First got my CHL in 2009. Only owned 2 guns at that time, a rifle and a subcompact .45 Taurus (the PT145). Shot a 248 or 249 on the CHL test and thought I was pretty hot stuff for it. Once I starting learning and shooting more, I discovered that the ability to hit a man sized target with a pistol on a static range is pretty much the smallest part of being proficient and ready to defend yourself with a pistol.
I originally started carrying the PT145 in a Crossbreed supertuck. It was comfortable enough and the gun worked fine, but the trigger wasn't great.
That was replaced by 1911s for a while, in both an IWB Crossbreed and some Galco OWB holsters. Much better triggers, fun to shoot and easy to conceal. I really enjoyed the full size 1911 but learned that those can get a little heavy on hour 12 or so of wearing one.
At this point, my EDC is usually a Glock 19 in a leather OWB holster (or occasionally a J frame in the front pocket or ankle if absolutely necessary). I traded size and a nice trigger for capacity and a usable trigger, but most importantly lighter weight. I really like OWB holsters now, and while IWB holsters will always have a place in my carry rotation, if I can choose I far prefer OWB.
And my gun collection may be slightly larger than 2 at this point.

In summary, in the last 5 years I've learned that concealing a handgun can be incredibly easy and comfortable, even in shorts and a t shirt with the right holster and belt, that when you're going to carry a gun around all day ounces really do matter, and that I will always have more to learn on the road to becoming a proficient pistol shooter. I have still not had to draw my pistol to defend myself, and hope to report back in another 5 years with nothing having changed on that front at least.

I'd also like to say that Texas continues to improve its gun laws, in no small part due to the hard work put in by folks like Mr. Cotton. When I first got my CHL, it took 102 days to get from mailbox to mailbox. I just renewed online less than 2 weeks ago and am already through with everything but the manufacturing of the license. What a great change! Soapbox time: Join the NRA and TSRA so we can talk about how much better guns laws have gotten in another 5 years.


So the question I put to the rest of you is simple: How has your gun/carrying techniques changed since you first got your CHL?
