Red dots are fantastic, especially for aging eyes.

Today I got out to the range with the Springfield again. I'm getting better with this green-dot Holosun. The 45's are printing well from 3-25 yards. I swapped to a handload I used as long as 40 years ago 200 grain cast LSWC bullets over 5.0 grains of W231 for about 800 fps. Yes, I missed one at 25 yards: View attachment 28664

Very nice shooting Guy. I had two Holosuns installed on my Kimber .38 Super and .45 a couple months ago, it had to have the rear sight knocked out to install a base in the dovetail to be able to adapt the Holosun. I see you still have that rear sights on yours behind the Holosun. I have contacted Kimber before for information and their response was that they cannot machine the top of the slide to install the base since the top of the slide is not thick enough and it will affect the mechanisms under the slide on the Kimbers. How were you able to get it machined or did you get the gun with the top pre machined?

This is the model of Ronin that comes with easy to detach rear sight, leaving a spot perfectly machined for a sight base. Springfield uses the "Agency Optical System" which is a series of different mounting plates for various dot-type sights. One advantage is that the sight base includes an integral rear sight - which can be used if something goes wrong with the red-dot sight. When I bought the Ronin, it also came with an $80 discount coupon for the sight base.

I'm impressed with how well thought-out and well built their system is. I think Kimber offers something similar in a factory gun now. I was going to put the Holosun on my newer Kimber, but instead I traded the Kimber and some cash for the new Springfield Ronin. I like both the Kimber and the Ronin, but wanted to try the Springfield setup.

Re target loads, I've got a few hundred of the 200 grain LSWC cast bullets on hand AND I think 2,000 or so Nosler 185 grain JHP bullets which are wonderfully accurate. Maybe 3,000? Couple those with some Titegroup I think and I'll have a mild shooting, accurate target load.

BTW ol Roy Yeager tells me that is one heck of a whitetail bullet!

Very nice Guy.
As for the 185gr Nosler JHP the AMU load is 4.3grs of N310, that load will hold under 3" at 50yds in a well-tuned 1911 .45.
Tite group with the same charge should do well also, 750fps-800fps is the sweet spot for that bullet.

Wow, that Ronin interchangeable system is very nice stuff. My Kimbers are the older models, but still looking new. Shoots great with the Holosuns on it as well. I like the newer models where it already has the ramp feature to install the Holosuns.

Thanks for the info on that load - I knew it was available - but I don't have any N310 on hand. Perhaps I shall get some!

Yes, I missed one at 25 yards:

Nah , that was a warning shot
Red dots are the way to go I’ve added them to my shotguns and revolver.

 

[JD338]

Good point on putting a red dot on the shotguns Rick. Our turkey guns have red dots and they are deadly on those big toms.

Picked up a new Springfield Ronin 1911 in 45 ACP in December, put 50 rounds through it within minutes of buying it. Excellent performance. My only complaint is that the thumb safety feels mushy when putting it on safe. Nice click though when taking it off safe. The sights are big and bold with a fiber optic sight up front. Nicely finished pistol. Accurate and reliable. I've been favorably impressed with "dot" type sights for quite a while now, decades, and bought this version of the Ronin because the slide is already cut for optics. Springfield also sells optics mounting plates that fit right on their pistol and the gun comes with a coupon for a good discount on the plate of choice.

This Holosun 509T is a "closed emitter" meaning that the laser is well shielded from dirt and the elements. It has the "shake awake" feature and the emitter goes to sleep after 10 minutes with no motion. As soon as the gun is picked up, the reticle of choice pops right up. There's a choice of a 2 MOA dot, a large circle, 32 MOA I think, or the circle with a dot in it. Also there are numerous brightness settings for both daylight/ambient light and also several for use with night vision. It's a good unit. I got mine with the green reticle.

The Holosun comes with a small tool for mounting it and adjusting the windage & elevation. I used a Wheeler inch-pound torque driver to mount the optic plate and the sight itself, but used Holosun's little screwdriver tool for the adjustments.

Fired only 230 grain CCI Blazer FMJ though it so far. No malfunctions. Good accuracy. I'll get back to my handloads in due time.

This was the only 1911 holster I had on hand that was cut for optics. I used this holster for a while as a concealment holster when I was a cop. It's a Blackhawk Serpa, but not the one with the infamous "button" which has been deemed unsafe by many.

Final 7 yard sight-in target. Yup, I messed up and put that one out left of the group. BTW, this zero also worked well out to 25 yards, the limit of the indoor range where I was shooting.

Regards, Guy

The 509T is a solid choice for a closed emitter. That mushy safety on the Ronin is a common complaint though. You might need to file the detent slightly or check the spring tension to get a crisper click
