Personally, I would first look out for a good local gunsmith and someone who can do warranty work.
I just happen to live close to the S&W (
And others) Canadain warranty center and gunsmith shop.
I for my first 1911 I picked up an S&W. I thought I wanted a Colt, but after seeing all the issues with
Colt, and the fact I already had an S&W 586 that has been great, heading to stainless steel S&W1911 was an easy choice.
Having a local gunsmith and brand experts close buy, I can get 1911 updated as skills improve and keep the warranty intact.
I walked in on the day I picked up the pistol and asked for a fibre optic front sight and trigger job. I was told they would upgrade the sight but would not touch the trigger until I shot 1,000 rounds through the gun, at which time they would address any issues I still had with the trigger.
Rather than just take my money, they explained that after 1,000 rounds much of the factory issues should be worn (and polished) out. Polishing a trigger before it is properly broken in can cause the trigger to fail over time. Some have gone so far as to dump an entire mag on full auto.
BTW I also bought a used and tuned GSG 1911 .22. It shots rather well, and I start out with each session at the range with the .22.
Most days I work out the rough edges with the .22 and then move on the .45 $$
If I am not shooting well with the .22 I just call it a day and pack up and go home.
The .45 is rather expensive to shoot when having a bad day at the range.
