Frame and slide cracks in semi-auto pistols, what brands do the most?

[His lordship.]

What brands and calibers of semi-auto centerfire pistols cause the most problems in slide and frame failures, what are the least likely to cause problems?

Thinking of adding another pistol to my collection, have Rugers, a Glock M.17, a CZ-75, a Bulgarian Makarov, and a Springfield XD9 right now. Used to own a Taurus made Beretta 92, a post-war German P-38, a Czech 52, Chinese Tokarevs,  Raven P-25, and a Phillipines made Colt 1911.

Thanks.

Early Glock 22's often cracked around the locking blocks, Sig P series alloy frames when they first went to .40s&w, Colt Delta Elites in 10mm, that's about all I can think of off the bat.
The Glocks went through many changes with the frame rails, locking blocks and pins to handle the .40 and .357sig.
The Sigs have been redesigned and are now some of the best .40's out there.
The Delta Elite is no more.

You don't have any worries regarding this with ANY modern quality semi, shooting modern, quality ammo.

I believe the Delta Elite is back in production and I do not recall hearing or reading of any frame cracking with that particular model or any of the 1911s, either colt or others.

From the Bren Ten website:

Delta Elite - In 1987 Colt rescued the 10mm Auto cartridge from an early demise by chambering the round in its 1911 Government Model. Dubbed the "Delta Elite," Colt advertised the gun's hard-hitting power and flat trajectory.

The Delta used a dual recoil spring setup rated at 23lbs, but even with the stronger spring early guns developed problems with frame cracking. Cracks appeared in the corner of the slide stop hole, but Colt was able to come up with a simple fix by removing the metal just above the hole turning it into an open-topped notch. Though this solved the frame cracking issues, the Delta was never able to totally overcome the continuing rumors of poor durability and stories of guns being "beaten up" by the 10mm cartridge.

I guess they fixed it before they went out of production.

Most of the Delta stress problems were found ath the baseof the trigger guard. this was corrected byundercutting the guard and relieving the stress point.
There was, for some time, a call for the 10mm but just as quickly as the fever caught it went away. There were a number of Custom Smiths who built, and still will, a 10mm on your gun, the cost seems to be extravagant however.
The 10mm is just a little TOO hot for praticalcarry--the 9x23 is a better choice---and the .45 still reigns.
For wood carry where you can expect bears--it is an OK gun.
No bears on the Gulf Coast however.
I was not over fond of the Delta I shot.
