All the old Hi standards are great, The "military " grip came out after the 103 series I think, 104, the grip is the same shape as a colt 1911
I like the older slant grip models, but for big hands the military grip may be better.
All the barrels on the 103 and up will interchange, the sights are different on some of the models.
I prefer the Victor models, full sight rib, I use to find them for 4-500, now mint one are x2 that.
There is a nice one on the exchange now, higrade shooter, but not a collector grade.
The sharpshooter, tornament, citation, trophy , victor are the same guns, but better finish as you go up in models ,
And the top models have adj. triggers, But it is better not to mess with the triggers, easy to screw them up.
And if you ever see a 10X the is the holy grail, all hand fitted for top compt.
I still have a few springs left NOS, nut the parts from the new Taxas ones will work.
The mags are exc. if you know what to do, aftermarket are usally poor.
While the S-W 41 guys are cleaning the chambers on their guns, the hi standards are still shooting.
The good older models smiths are getting damn expence also, nice, but have never like the grips .
Hope this gives you some infor., And Never pass up good used mags
P.S. price , I has changed in the last few years , I use to deal lots of them in the 4-500.oo range, but seem to be in the 750.oo area now
Victors 8-900, 10X 3000.oo????
