Springfield XD (M) or Walther P99?

I'm looking to buy my first gun of 9 mm and reduced to two. I was wondering if any of you have shot one or both their views and experience, that has the best value, accuracy, features, reliability and ergonomics? The ability to disassemble the P99 with a button is a feature I really like. The XD (M) is the trigger that I favor more. I have only shot the P99 fits my hands decently well. I'm looking for point- fire once or twice a month for the enjoyment, not self-defense or export. In addition, any other suggestions for a 9mm are also welcome.

If you like cock-function ..... then you are looking at the wrong weapons. I would take the XD in the day! Walther, but you have to look at new 9mm FN FNX. Has 17 rounds, has a 4 "barrel, a great" usable "de-cocker/safety, and weighs only 22 oz

Description

The International Ergonomics Association (IEA) is currently developing standards for Ergonomic Quality in Design (EQUID) which primarily intends to promote ergonomics principles and the adaptation of a process approach for the development of products, work systems and services. It is important to assess the ergonomic quality of products, hand-held tools and computer input devices through working processes that represent reality. Well-designed working tools can be expected to reduce or eliminate fatigue, discomfort, accidents and health problems and they can lead to improvements in productivity and quality. Furthermore, absenteeism, job turnover and training costs can positively be influenced by the working tools and the environment. Not all these short-term and long-term issues of working tools can be quantified in pragmatically oriented ergonomic research approaches. But multi-channel electromyography, which enables the measurement of the physiological costs of the muscles involved in handling tools during standardized working tests, and subjective assessments of experienced subjects enable a reliable insight in the essential ergonomic criteria of working tools and products. In this respect it is advantageous to provide a test procedure, in which working tests can be carried out alternating both with test objects and reference models.IOS Press is an international science, technical and medical publisher of high-quality books for academics, scientists, and professionals in all fields. Some of the areas we publish in: -Biomedicine -Oncology -Artificial intelligence -Databases and information systems -Maritime engineering -Nanotechnology -Geoengineering -All aspects of physics -E-governance -E-commerce -The knowledge economy -Urban studies -Arms control -Understanding and responding to terrorism -Medical informatics -Computer Sciences

Description

This book focuses exclusively on ergonomics in the design and use of hand tools. Hand tools have been an integral supplement to the human hand since the beginning of civilization. Recently, they have been pinpointed as a prominent cause of workplace disease. Cumulative Trauma Disorders such as Tendonitus, Carpal Tunnel Syndrome, and Raynaud's Syndrome are caused by the specialization of motion employed when using a screw driver, the shock to the hand and wrist when a hammer strikes a nail, or the vibration of a power saw. Ergonomics and Safety in Hand Tool Design explores the relationship between Biomechanics, Safety, and Ergonomics allowing the reader to recognize, evaluate, and control ergonomic risk factors and improve hand tool design.After a history of hand tool use and design, the book is broken down by the various disciplines as they apply to hand tools, taking a broad approach. The author gives special attention to safe design and use, illustrated with detailed diagrams. The text serves as a guide to the human factors in safety and ergonomics for safety professionals.

This digital document is a journal article from International Journal of Industrial Ergonomics, published by Elsevier in 2005. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.Description: As a simple solution to alleviate problems associated with manual material handling, manual vehicles, such as carts, trucks, wheelbarrows, etc., are often provided to operators. This review was initiated by concern for the effects of design, task, environment, and operator factors on the usability of manual vehicles. The previous studies are summarized and then ergonomic recommendations are made for each factor. Most studies have been performed on four-wheeled carts and focused on wheel design, handle height, load weight, moving direction, motion phase, and floor type. Biomechanics, psychophysics, and work physiology have been used to help understand usability. For future research, the systematic classification of manual vehicles is necessary to make specific ergonomic recommendations for special-purpose manual vehicles. Relevance to industry: Workers use manual vehicles to reduce physical stresses during manual material handling without the awareness of their factor effects on usability. This review paper would be useful for a manufacturer and ergonomist to design and select general manual vehicles.

Description

This digital document is a journal article from International Journal of Industrial Ergonomics, published by Elsevier in 2004. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.Description: An experiment was conducted to investigate the effects of work height, workpiece orientation, gender, and screwdriver type (Phillips or flat head) on productivity and wrist deviation during a repetitive screw driving task. Seven males and seven females (mean ages of 37.6 and 51.7 years old, respectively) performed the experiment. Males and females performed better with the Phillips head screwdriver. Although gender was not significant, the interaction between gender and screwdriver was, with females having a greater performance difference (30%) between the two screwdriver designs than males (10%). There were strong workpiece orientations by work height interactive effects on productivity and measures of wrist deviation. The implications of the results for workplace design, and comparisons to previous studies with similar experimental conditions are discussed. Relevance to industry: Enhancing performance in industry requires considering both the injury potentials of tasks as well as productivity concerns. In the case of non-powered hand tools, this requires selecting tools and designing tasks and equipment to minimize awkward postures and force requirements while permitting adequate productivity. The current study provides results and job design guidance for repetitive screwdriver use.
