A small powerhouse RPN scientific
1 of 1 found this helpful The HP 11C calculator has stood the test of time in terms of construction and function. It is compact and full of features. It can even be programmed by the user. The keys are hinged and tactile so they do not wobble and provide positive feedback. If you can find one on eBay for less than $100, grab it or a 15C. They'll both serve you well.

Real factory mags
2 of 2 found this helpful These are factory Hi-Point mags just like the description says. They should not require any break-in or modification to run perfectly in your C9 or CF380 pistols.
I ran brass and steel cased ammo without a single malfunction in two of these mags.

Capable, well-built RPN calculator from HP
5 of 5 found this helpful I should emphasize that I have not used this calculator's financial functions at all. Keep that in mind through the review.
I bought two of these calculators to convert them into WP 34S and WP 31S scientific calculators. I used one for a week before I converted it. The keyboard is excellent, using hinged, hard plastic keys for a noticeable tactile response and no key wobble. The display is split between a dot matrix section which displays the action performed, and a standard seven-segment section that displays numbers, primarily.
Probably my favorite feature of this calculator aside from RPN entry is the trig functions and "Math" menu. Other than the very similar HP20b, I have not seen a financial calc that can operate as an entry level scientific.
The only real bad part about this calculator is they stopped making it. One of the two calculators I received had two keys that required some time and manipulation to free up a bit. They had a dull action at first. I don't know if it was a quality control issue or a result of how it was stored or shipped, so I'm not taking any stars away for it.
They have data connection ports for updating and replacing firmware, which is how they can be converted to other calculators. Research the WP 34S project if you want to know more.
