I am working on a friend .45 XD now and I love that it has a sear spring like a SIG's very well thought pistol. I also found a site to get good deal for XD parts that at times are hard to find. here is the Url: https://www.pistolgear.com/products.php?id=15
Hi Keith, if I understand, you were asking whether it's better to get something basic like a Milspec, or get another Springfield 1911 with more features.
It all depends what you want, but if your goal is to get a basic pistol and build it up with quality, custom parts over time, you would do better to just start with a basic Milspec, and then add the parts that YOU choose when you customize it. If you get one of the more expensive Springfield models, such as the loaded models, they have some nice features, but tend to compromise and to use a lot of what are known as MIM parts, which are not quite as high quality and long-lasting as the custom steel parts that people commonly get to upgrade a 1911.
I did the work on my friends XD and the kit made it very easy to do yourself it dropped the trigger by 2lbs. I did a little tweaking of the springs they are close to a SIG's Sear Spring. For a $20.00 kit it was well worth it.
Just got my Service XD45 back from Robar, they NP3'd the whole thing, very very slick now. Carry my 1911 Les Baer all the time, my XD45 is my "night stand" pistol, (14 rounds of 45acp in a 1911 grip, you just can't go wrong)
The work I did on the XD .45 I worked on for a friend worked like a charm. The trigger broke like glass at 4lbs but felt less and functioned perfectly. For a nice trigger job buy the spring kit from Canyon Creek and order the parts and install them you will have a smoother trigger and at least 2 Lbs. lighter on. I highly recommend them.
