If you’re new to the firearm scene you should get as much information as you can then put your $$ on something you will not regret because it’s getting worse to try to buy and sell guns here.
When I decided to downsize many pistol calibers down to one, I wanted to get 2 guns that the wife and I both liked. We went to the Marksman in Puyallup because 1) they had an indoor range AND 2) they had gun rentals.
We shot 9 different brands in 40S&W and while those popular brands like Glock, Sig & HK are popular they either didn’t fit our hands or didn’t group well. We both liked the Springfield XDM40 with a 3.8” barrel and bought one subcompact and one with a full size grip.
Also, get involved right now to help thwart the gun haters anti-gun bills they are pushing as we speak.

5'6", 155, carry G19 or G17 with optic all day long, no matter what clothing. I don't generally run a wml, but it is doable if needed.

JMCK AIWB, even in shorts and sleeveless shirt in summer. Ain't nothin'. OWB at times as well, in different clothing, and works just fine (Blade-Tech Total Eclipse).

Look around the larger community, there are a boatload of average or smaller frames guys who carry a G45 or similar every day, concealed. It's common.

For the OP, this illustrates a "different strokes for different folks" aspect of carry and defensive shooting. Experimenting with different methods and modes of dress will help you find that "sweet spot". Don't dismiss that gun as a perfectly viable option just because of one guy's opinion.

Getting some formal training also will yield dividends. You'll be best prepared with whatever/however you carry if you can meet the "2 second rule", simply drawing from concealment and getting at least one good hit COM in 2 seconds or under. All it takes is practice and the right gun/carry method.

You're on your way! That G45 is a great pistol.

5" 6" and 155lbs ??? You sound so much Taller on the Internet Vin. (Smokey and the Bandit reference)

I'm not discouraging him away from that G45, and I agree with Steve on it for a Range gun or nightstand gun for things that go bump in the night. It's just a Large pistol for everyday carry.

If he can do it, props to him (and you Vin)

I think you are talking about Rain City which was champions and has a new owner now. In terms of gun stores its a meh for me. But yea I would love to make some gun friends. My ol' lady is about on her wits end with me talking to her about this and that, gun wise that is. Same goes for my other friend.

You are new to carry so yes it is a bit of weight but you will get used to it. That G45 is puny compared to what I have to carry now when I go to the cabin because Spring is on the way and the bears are waking up. The right holster makes a big difference and the more you carry the more you get used to the weight. Have you decided on the position you want to carry? Now that you made the mistake about fit for your hands do not make the same mistake with your wife if you can get her to shoot. You really have not shot that much so it could be a combination of that and your grip.
